Toall whomo'tmay concern:

Be it known that I, CLARE A. Dean, a citizen of-the United States, and a resident of the city of Harvey, county of State of Illinois, have inventedcertam new and useful Improvements in Lighting Sys: tems for Vehicles, of which the' fol-lowing s a specification. g a

My invention relates to lighting systems for vehi les, and more specifically to a lighting system designed for use especially in street or railway cars, for li hting the entrain-e, ei'itrance-ste'p, and t e ground or platform adjacent the entrance-step sons to prevent injuries such as frequent! result by reason of the non-lighting of t e locations mentioned, when entering or leaving The object of my invention is the production of a lightin system as mentioned, which will be simple and economical in com sircc't oh audeilicient in operation.

Other objects will appear hereinafter.

myinvention "hatter: described and My invention will be more readily under; stood by reference to the accompanying drawing forming apart of this specification, and in which- 1 Figure 1 is a fragmentary shftiiyial side elevation of one end portiongof i conventional street car equippedwitlr system embodying my invention, Fig. 2 is a fragmentary sectional front elevation of the car.

Referring now to the drawing, 1 designates a street or railwaycar. of conventional form,provided at each end with a sliding limi' 2 for gaining aecess to the interior of the car. At. the door 2 is provided the usual entrance-step 3' which is utilized on entering or leaving the ear. Arranged within thecar vestibule above the door 2 and ad acent which are included in an electric circuit 5, the latter, if desired, being the usual line circuit of thefcarn. Coiiperating with the lamps 4 is a reflector 6 adapted to reflect or direct.- the light gcnerate'd'downwardly and outwardly so that, when the door 2 iso en, the do rway, platform or "round adjacent said step will interposed in the circuit 5 is a suite 5 T in which are included two spring 7 arms 8 adapted to Cook, and

' when. the lighting secure such" lighting or operation 7 or cutting out 'fot'th will be found etlicient in'use and lighting} the step 3, and a portion 0 the normally contact with each other so as to close the circuit, spreading of arms 8 effecting opening of said circuitl The arms 8 are arranged adjacent the 50 iamb latter perinw ed, w

be positioned between the 8 ,to cited the spreading thereof and hence to open the circuit including the lamps 4. With this arrangement it will be seen that the lamps 4 will be in operation only when the door 2 is in open position,

of the doorway and step 3 is desired, said lamps being-inoperative when the door is in closed position. However, it may be'desiredto contin-ually'opcrof door 2','the adjacent edge of the being provided-with a pro ectm tastud J of insulatin material a aptate lamps 4' in order to illuminate the 'vcstib3112 or interior of thelca'r, and in order to of said himps a bridge-'lttis employed for bri ing ofbi-idge-IO v i'ch wi-llalordinarily. be open,- said vswitch. being closedonl-y when. a continuous burning or operation of the lamps 4 is desired. "A switch. 121s also preferably interposed inthejcircuit 5 which controls 3.5 th e'entiresystem.

i A' lightingsystem'of the construction set economical in the consumption of fuel or electrio energy, s 'stein if desired, may be so adjusted that t e lightingmeans will be in o oration only when the car door is open or only at the time when illumination of the doorway, entrancestep, the eiitrance-step is of advantage.

'VVhile I have illustrated and described the preferred form of construction for carrying my invention into efiect,- this is capable of variation and modification without dep'art- 100 ing from the spiritwof the invention. I, therefore, do-not wish to be limited .tothe exact details of construction set forth,-but

desire to avail myself of such variations and modifications as come within the scope oft-105 the appended claims;

Having Patent, is:

1. The combination with a vehicle having lio en said door is in c'osed position, to

contacting arms 55- hence only 7'0 the switch: '1. A switch a ton 11. is--interEosed inthe conductor wire 50 reason :of the fact that the and. the ground or platform adjacent described my invention, what I?"- clnim as new and desire to secure by Letters-- means arranged to illuminate said doorway ing means included in said circuit and-ar-- ranged in said vehicle above said door; a"

reflector cotiperating with said lighting: means for directing the light generated toward the doorway and said step, and a} switch controlling said lighting means,

whereby said light will be inoperative .whenf said door is closed and operative when said. door is open; and meansin said circuit for bridging said eration of said lighting means, as described.

8. The'combination with a vehicle having a movable door, and a step positioned at said-door, of an electric circuit; an electric switch to efiect continuous opsubstantially lighting means included in said circuit and arranged in .said vehicle above said door; a switch controlling the lighting means whereby said lighting means will be inoperative when-the door is open; and means .in said circuit for bridging said switch to eifect continuous o eration of said lighting means, substantiy.as described. '4, The combination with a vehicle having a movable door, and a step positioned at said door, of an electric circuit; an electric lighting means included in said circuit and arranged in said vehicle above said door; a reflector cooperating with said lighting means for directing the light toward the doorway'and said step; a normally closed switch interposed in said circuit; means carried by said door adapted, when the latter is in closed position, to open said switch, and

means in said circuit for bridging said switch to effect continuous operation of said lighting means, substantially as described.

{3. The combination with a vehicle having a movable door and a step positioned at saiddoor, of an electric circuit; an electric lighting means included in said circuit and arranged in said vehicle above said door; a

reflector cooperating with said lighting means for directing the light toward the doorway and said step; a normally closed switch interposed in said circuit; means operative by said door adapted, when said door is in closed position, and means in said circuit for bridging said switch to effect continuous operation of said lighting means, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
